ENGLISH
E
High pressure switch (HP)
trips.
E1
Fan does not work.
E1.1
The refrigeration
compressor and the fan
stop.
Repair or replace the fan.
Where fitted, check the
thermal protection switch of
the fan.
Press the reset button on the
cap of the pressure switch.
E2
Ambient air temperature
too high.
E2.1
• Air ambient temperature
higher than maximum
permitted value;
•
see E1.1.
Reduce ambient temperature
within design limits, for
example by increasing local
ventilation.
Press the reset button on the
cap of the pressure switch.
E3
Recirculation of warm air
due to incorrect
installation location.
E3.1
• Condenser cooling air
temperature higher than the
permitted value;
• see E1.1.
Change the position of the unit
or the position of any adjacent
obstructions to avoid
recirculation.
Press the reset button on the
cap of the pressure switch.
E4
See A4.
E4.1
See E1.1.
Clean the condenser fins.
Press the reset button on the
cap of the pressure switch.
E5
See A5.
E5.1
See E1.1.
Remove obstruction from
condenser intake.
Press the reset button on the
cap of the pressure switch.
E6
See A1.
E6.1
• Water outlet temperature
too high;
• refrigerant compressor
stops.
Restore the thermal load to
within the preset limits.
Press the reset button on the
cap of the pressure switch.
F
Compressor protection
tripped (hermetic
compressors klixon).
F1
Thermal load too high in
conjunction with high
ambient temperature.
F1.1
• The head and body of the
compressor are very hot;
• the compressor stops and
attempts to start after a
brief period.
Stop the machine and restore
the load within the preset
limits.
Wait a few minutes before
restarting.
F2
Thermal load too high in
concomitance with a lack
of refrigerant in the circuit
(also see A5).
F2.1
See F1.1.
Get a engineer to check for
leaks and eliminate them.
Get the engineer to fill the
circuit.
F3
See points from E1 to E6.
F3.1
See F1.1.
See points from E1 to E6.
G
Fuse FC1 trips (TAEevo
Tech MINI 08-10
models).
G1
Compressor motor
overloading or short
circuit, or short circuiting
in the compressor power
line.
G1.1
The compressor does
not start even if the
thermostat function so
requires.
Using a tester, check the
motor windings and the power
cable.
Replace the compressor or
cable if necessary.
Change the fuse.
H
Fuse FF1 trips (TAEevo
Tech MINI 08-10
models).
H1
Fan, pumps and electronic
power overload or short
circuit in the power line.
H1.1
The fan and electronic
board do not work at the
same time even if there
is electric power.
Check the components and
wiring with a tester.
Replace the damaged
component or wiring.
Change the fuse.
